1.Make sure to use throttle/carb cleaner, not brake cleaner, which
could destroy plastic bits and does not contain any lubricants.
2.If you can get to the potentiometer, hit it with Caig's MoveIT
moving contact cleaner. If it is an enclosed potentiometer, really
get it covered- some will work its way in to the contacts. Actuate it
a bunch of times, then use compressed air to blow it clean, repeat
once or twice. As long as the tracks are just dirty, it should work
great afterwards. If they're damaged, well...then you're kinda
screwed, unless you can find a very close replacement for the pot.
Since gunk will affect the resting position of the throttle, it may be
beneficial to re-calibrate the throttle?
